GetoptLong Accessing the values with out looping

Yes, it sucks. That's why I wrote the 'getopt' package.

gem install getopt :slight_smile:

require 'getopt/long'
include Getopt

opts = Getopt::Long.new(['-d', '--date', REQUIRED])

if opts['d']
   # ...
end

Makes perfect sense in this example you are still looping
through the options. All though this is better on the eyes.

I was hoping that the instance of getoptlong had some kind of
method to get the value of one of the command line options.

nice dan. i've been using optparse for all my stuff but it's usage is a bit
obtuse. perhaps i'll switch... does it support parsing arbitrary arrays or
only ARGV?

regards.

I am having an issue with the script working. Is their some path variable
that needs to be set for ruby to see the gem packages?

Initially i have the ubuntu ruby pkgs installed. I have removed them and
built ruby 1.8.4 and gems 0.8.11 built from source.

Any ideas?
